RAZOR-STROPPING MACHINE.

Specification of Letters Patent.

Patented June 30, 1908.

To allwhefln it may concern:

Be it known that I, AUGUsT \VILLIAM SCHEUBER, a citizen of the UnitedStates, residing in Jersey City, county of Hudson, and State of NewJersey, have invented certain new and useful Improvements in Razor-Stroppin Machines, of which the following is a ull, clear, and exactspecification.

My invention relates to machines for stropping razor blades and isarticularly useful or stropping detachable lades such as are used inmany safety razors. It may also be used for stropping the blades ofordinary razors.

The invention has for its object to provide a Si111pl6,&11(l. economicalstructure wherein the blade shall be securely held and exposed,- withslight movement, to the action of the tra and wherein tie blade holderis dicct T connected with, and controlled by, the friction roller, andthereby doing away with gears and separate s rings to operate and returnthe parts, an providing a structure which is not liable to get out oforder nor Wear out quickly.

The invention consists in a pivoted bladeholder and a pivoted frictionroller adjacent and. directly connected thereto by a connection whichrocks the blade holder in the opposite direction to that in which thefriction roller is rocked, and by the spring action of which the bladeis quickly returned to central position.

It also consists in sundry details of cons'truction hereinafterdescribed and illustrated in the accompanying drawing, wherein Figure 1is a side view of my improved stropping machine, partly broken away;Fig. 2 an end view t iereof; and Fig. 3 a vertical section taken 0 theline 33 of Fig. 1.

The side frames 1, 2, are connected by a series of rods 3, 4, 5, 6, and7, and by a supporting loop 8. RodS is principally a connecting or.ytrcngthening rod, although it also serves 'to maintain the strop inposit-ion. Rods 6, 7, guide the strop and maintain it in pro )erposition to engage the blade.

pon the rod- 5 is mounted the bladeholder 8, which, as illustrated, ismade of a single piece of stiff material adapted to hold its shape andpossessing resiliency such as thin sheet iron or, steel, although, ofcourse,

IZdo not confine myself to a single-piece structure. 'This blade-holder8 is constructed with a central, longitudinal channel 9,

'vided with the blade-receiving lips 10, W

formed by bending out its material, and into this channel rod 5 enters,and ermits the blade-holder to rock freely t ereon. Upon its lower sidethe blade-holder is roare bent substantially to the siape of the I backof the blade to be held, and owing to the slight-spring of the sheetmetal, will hold the blade firmly. The upper end of the blade-holder isformed into a tailiece or feather 1 1, through which the bladeolder isrocked and returned to central position.

A- semi-cylindrical friction member 12 is mounted to rock freely uponrod 4, and this is perferably formed of material such as is used for theblade-holder. This rocker has an upper friction surface 13 over whichthe strop 18 passes, and its lower part, on each side, is formed intowings or flanges 14, which receive the tail-piece 11. Midway of itslength each of the wings 14 has a portion of its material separated byslots from the main body forming spring tongues 15, which are pressedtoward the center and are in close contact at all mes with the feather-11, preventing all play of the latter and always tending to press theblade to central position out of contact with the stro The blade 16' isinserted in tlie holding lips 10 of the blade-holder from the end, andto permit this the side frames 1, 2, are cut away, as at 17, therebyforming two pendent portions in each. frame, which receive theconnecting and strop-guiding rods 6, 7, at their lower ends.

The operation of my device is exceedingly simple and certain and will bereadily understood. The strop and blade being in position and the devicebeing suspended by the loop 8, the strop is grasped at the ends by eachhand and pulled first one way and then the other, and the strop, bearinon the friction rocker 14, will cause the biade to be rocked, bringingit into position to be stropped by the descending side of the strop: c.9., in Fig. 3 the left-hand portion of the strop is moving in thedirection of the arrow, and the razor is then rocked to stro pingposition in contact with that part of't 1e strop. This will cause rib 11to press the oppositely disposed spring tongues 15 apart (Flg. 3),thereby flexing said springs and operating to return quickly the bladeto central position the instant the movementof the strop is reversed. Areversal of'the movement will cause the razorto engage the opposite partofthestrop. -This arrangement ossesses many advantages, among others, te quickness of responseof the razor to the. friction rocker; the absenceof play between them; the doing away with wire parts of the frameforming the inner walls of recesses 17 may form sto s to limit therocking movement of the b adeholder.

It is obvious that many modifications and changes may be made in myinvention without departing from the spirit thereof, and I do not meanto limit myself to the gxact construction shown and described,

What I claim and desire to secure by Letters Patent is;

1. In a stropping device, strop guiding means, a'friction rockerdisposed in operative relation to the strop, pendent flanges on'saidrocker, spring ton ues in said. flanges, a blade-holder pivota ysupported in said device, blade-holding means in said blade holder, anda projection therefrom adapted to be received between said pendentflanges and to be embraced by said spring tongues, substantially asdescribed.

2. In a stropping device, side frames, strop guiding and connecting rodsmounted therein, a friction rocker mounted to swing therein, pendentflanges thereon, spring blade-holding lips therein, a blade-holdermounted in said frames to rock, and a pro-I j ection' adapted to enterbetween the flanges and to be embraced by the spring tongues of therocker, substantially as described. v

3. In a stropping apparatus, a rocking device having spring tongues,and-a blade holder having a projection adapted to pass between and beembraced by the said spring tongues and to flex the same whenoscillated, substantially as described. *4. In a stropping device, sideframesrecessed at their lower parts, strop-guiding rods connecting saidlower parts, a friction rocker mounted to swing in the frames, integralflanges" depending'from said friction rocker, spring tongues in saidflanges, a blade-holder mounted to rock in the frames, a projectiontherefrom adapted to pass between said fianges and spring tongues, andspring blade-receiving lips, said projection and ii s formed in onepiece, substantially as descri ed.

5. In a stropping device, side frames 1 and 2, recessed at 17,connecting" and guiding rods 6 and 7,. connecting and bearing rods 4 and5,.friction rocker 3 on rod 4, pendent flanges 14 and. spring tongues 15integral therewith, blade support 8 on rod 5, comprising rockin feather11, hearing channel 9, and spring ho ding lips 10 in one piece, saidlips 10 extending within recess 17 substantially as described.

In testimony whereof, I have hereunto set witnesses.
